JOSEPH O. NUVER, OF ALLENTOWN, PENNSYLVANIA, ASSIGNOR TO I. A. HALL dzCOMPANY, OF PATERSON, NEW JERSEY, A FIRM.

SHUTTLE T 0 all whom it may concern:

Be it known that I, Josnrn C. Never, a citizen of the United States,residing in Allentown, Lehigh county, Pennsylvania, have inventedcertain new and useful Improvements in Shuttles; and I do hereby declarethe following to be a full, clear, and ex-,

act description of the invention, such as will enable others skilled inthe art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, and to letters of reference markedthereon, which form a part of this specification.

My present invention relates to shuttles for looms and it consists incertain improvements in the means for mounting the spindles whereby amore substantial, durable and practical shuttle is produced. As commonlyconstructed, the mounting for the spindle of a loom shuttle involves theuse of several pins which are driven through the walls of the shuttlehorizontally and cooperate with a bent steel spring to hold the spindlein its proper elevated or depressed position. It is well known thatthese pins operate sooner or later in many cases to cause the wood ofthe shuttle to split; besides, they are likely to work loose laterally,and by projecting effect damage to the reed and other parts of the loom.Again, the spring referred to occasionally breaks and falling into thewarp produces a smash. These several disadvantages are of course allattended with loss of time and labor in the making of repairs and inkeeping the shuttles in proper working condition.

My present invention has for its object to provided a mounting for thespindles of shuttles whereby the several disadvantages above pointed outas existing in the use of the mountings for shuttle spindles nowcommonly employed will be entirely overcome.

A still further object of my invention is to provide means whereby thespindle may be adjusted with reference to the longitudinal axis of theshuttle when the spindle is depressed, thus making it unnecessary forthe weaver to resort to the usual expedient of pressing down on the freeend of the spindle in order to effect the adjustment, which action, asis well known, often has for its effect to split the wood of theshuttle.

My invention is fully illustrated in the accompanying drawings, wherein,Figure 1 is Specification of Letters Patent.

a top plan view of the improved shuttle;

Fig. 2 is side view thereof, a portion of the near wall of the shuttlebeing broken away to show its internal construction; Fig. 3 is a planview of the spindle and its mounting removed from the shuttle; Fig. 4tis a transverse sectional view in the axis of the screw which holds themounting in place; Fig. 5 is a plan view of the blank from which the boxor casing of the mounting is produced; Fig. (3 is a longitudinalsectional view of a modified form of such box or casing; Fig. 7 is aplan view of the blank from which the box or casing of Fig. 6 isproduced; Fig. 8 is a plan view of the improved shuttle with a modifiedform of means for securing its spindle mounting in place; and, Figs. 9,10 and 11 are, respectively, a side view (partly in section), atransverse sectional view, and a view of a detail of the shuttle shownin Fig. 8.

In said drawings, a designates the shuttle body having the usual bobbincavity 1), 0 is a longitudinal extension of said cavity, the same beingformed open at the top, as seen in Fig. 'l but having an overhang orflange (Z. In the socket thus formed by the extension c of the cavity 71is arranged the box or cas ing 0 of the mounting for the spindle Inorder to form this box or casing, a blank 9 like that shown in Fig. 5 isfirst cut out of sheet metal, whereupon the portions h of said blank areturned up parallelto each other on the lines 2'; subsequently the lefthand ends of the portions h are bent around the curved rear edge j ofthe portion is of the blank which forms the bottom of the box or casing,while the right hand ends of said portions h are bent to form the jaws Zwhich serve to hold the bobbin or quill in proper position on thespindle when the spindle is depressed. Before shaping the blank to giveit the form of the box or casing, it has three pairs of holes m, a and 0punched in its portions h, and when the latter are bent up to form theside walls of the box or casing the holes of each pair are 0pposed toeach other.

The openings m and 0 receive the riveted pins p and y the same actingpartly to give stoutness and strength to the box and partly to supportthe spindle j and the plate-spring '1', said spindle having its butt 8fulcrumed on the pin Q and the spring 9 having its end It passed aroundthe pin p under the same and bearing against the bottom of the box orcasing and its other, end a engaging under the butt of the spindle. Informing the blank, it is provided in its portions with an opening '22which is designed to allow the downward play of the end to of the spring1* when the spindle is elevated.

The box or casing, carrying the spindle and spring, as just described,is fitted into the socket formed by the extension 0 of the cavity Z) byplacing the parts in the cavity and then forcing the casing back intothe socket, which it snugly fits, as shown in the drawings. In thisposition it is held against movement by the screw to which is driventhrough the sides of the shuttle and the holes a of the box or casing.The bottom of the extension 0 of the cavity is formed with a recess 00opposite the opening 4; of the box or casing so as to allow spring tohave full play downwardly when the spindle is elevated.

In the modification shown in Figs. 6 and 7, in addition to the side jawsfor holding the bobbin or quill in place on the spindle a third jaw 3may be cut out in the blank from the portion of the metal standing between that forming the side aws z, the aw 3 being then merely given thenecessary hook-shape, as shown in Fig. 6, so that, when the box orcasing has been completed from the blank and the jaw .2 correspondinglyshaped, the relation of the jaws y, z and 2 will be such that they willengage the bobbin or quill at three sides thereof.

In order to make it possible to secure the proper positioning of thespindle when depressed, I provide a screw 1 in its butt so arrangedthat, when properly adjusted by a screw-driver, its head 2 will bearagainst some fixed part of the shuttle structure, as the bottom wall ofthe box or casing. This screw may be conveniently reached by ascrew-driver for the purpose of adjusting it, and introduced accordingto the arrow in Fig. 2, whenever the spindle is elevated.

In place of employing a screw to secure the box or casing in its socketin the shuttle I find the construction shown in Figs. 8 to 11 in manycases preferable; opposed vertical grooves 3 are cut in the sides of thesocket formed by the extension 0 of the quill cavity and into these isdriven a staple a which fits snugly in its place in the grooves and isadapted to have its horizontal portion 5 (when the staple is drivenfully home and the box or casing is in place in the socket) enter therecesses 6 in the top edges of the sides of the box or casing. The-boxor casing can not now be removed without first raising the stapleslightly, which may be accomplished by prying it up. This construction,wherein the parts marked 8 and 6 form recesses open each transverselywith respect to the axis of the portion ofthe securing device a directlyreceived thereby, renders it even more unlikely for the shuttle tosplit, because no holes which would weaken it along the grain of thewood are necessary; it also avoids entirely the use of parts which mightwork loose from the side of the shuttle to effect damage as hereinbeforeindicated.

It Will be apparent that in any of the forms of my improved shuttle,should the spring 1" break, as occasionally happens, the pieces thereofwill not fall down from the shuttle to cause a smash but will be held inthe box or casing until the shuttle is removed from the loom.

Having thus fully described my invention, what I claim and desire tosecure by Letters Patent is:

1. The combination of the shuttle body, a spindle, a mounting for thespindle removably arranged in the shuttle body, and a device forsecuring the mounting in the shuttle body, said shuttle body andmounting having recesses to receive the securing device, one of saidrecesses being open transversely with respect to the axis of the portionof said device received thereby, substantially as described.

2. The combination of the shuttle body having a socket forming anextension of its quill cavity, a spindle, a mounting for the spindleremovably arranged in the socket, said socket being accessible to themounting from the quill cavity and limiting the movement of the mountingwhen introduced therein in directions transverse of the shuttle, and astaple interlocking the mounting with the shuttle against movementslengthwise of the shuttle, substantially as described.

3. The combination of the shuttle body having a socket, a spindle, amounting for the spindle arranged in said socket, and a staplestraddling the mounting and interlocking the same with the shuttle body,substantially as described.

4-. The combination of the shuttle body having a cavity therein andgrooves formed in opposing surfaces of said cavity, a spindle, amounting for the spindle removably arranged in said cavity in thegrooved portion thereof, said mounting being recessed, and a staplestraddling the mounting and engaging in said grooves in the shuttle bodyand in the recesses of the mounting, substan- 6. The combination of theshuttle body,

the spindle, a mounting for the spindle. consisting of a box or easingcomprising two side walls and a bottom wall, said bottom wall having anopening therein, pins eonneeting the side walls of the mounting and oneof them forming a bearing for the spindle, a bent spring extendingaround the other pin and having one end bearing against the bottom wallof the mounting back of the opening therein and the other end extendingforward and engaging the butt of the spindle, and an adjusting screwarranged in the under side of the butt of the spindle and adapted tobear against the bottom wall of the mounting forward of said openingtherein, said opening being arranged under the engaging portions of thespring and spindle butt, substantially as described.

In testimony, that I claim the foregoing, I have hereunto set my handthis 9th day of November, 1907.
